...S. G. Webster ABSTRACT The effects of emersion stress upon circulating hyperglycaemic hormone (CHH) levels in the edible crab Cancer pagurus were investigated using a highly specific and sensitive radioimmunoassay, with an antiserum directed against HPLC-purified C. pagurus CHH. Emersion resulted...

...Jum Sook Chung; Graham J. Goldsworthy; Geoffrey M. Coast ABSTRACT Achetakinin-like immunoreactive material in tissues and haemolymph of adult male crickets was quantified by radioimmunoassay. Achetakinin-like material was found in the brain, suboesophageal ganglia and the thoracic and abdominal...

...J. Eric Muren; C. Tomas Lundquist; Dick R. Nässel ABSTRACT Being interested in the distribution and function of insect myotropic peptides, we developed a sensitive radioimmunoassay (RIA) using an antiserum directed against the cockroach neuropeptide leucokinin I. The levels of leucokinin...

...S. Robb; P. D. Evans ABSTRACT The quantitative distribution of FMRFamide-like peptides in the nervous system and in their putative target sites in the locust Schistocerca gregaria is described using radioimmunoassay techniques. The nature of the immunoreactive material has been characterized...

...H. K. Lehman; D. A. Price ABSTRACT The distribution of FMRFamide-like material in the gastropod mollusc, Helix aspersa , was studied by radioimmunoassay (RIA) and immunocytochemistry. Most of the RIA activity was concentrated in the central nervous system, the male reproductive tract, the tentacles...
